Zeolite molecular sieves have the structure and characteristics of crystals, the surface is a solid skeleton, and the internal holes have the function of adsorbing molecules. There are pores connected to each other, and molecules pass through the pores channels. Due to the crystalline nature of the pores, the pore size distribution of molecular sieves is very uniform. Molecular sieves selectively adsorb molecules according to the size of the holes in their crystal, that is, they adsorb molecules of a certain size and repel molecules of larger substances, so they are figuratively called "molecular sieves."
4A molecular sieves can adsorb molecules with a diameter of not more than 4A, such as water, CH3OH, hydrogen sulfide, carbon dioxide, ethylene, C3H6, etc., and are mainly used for drying LNG and a mixture of gases and liquids.
4A molecular sieves have good adsorption and ion exchange properties, and are widely used in the detergent industry as a washing addtives to replace sodium tripolyphosphate (STPP) in laundry detergent. Toothpaste is a necessity in daily life. The main components of toothpaste are abrasives, wetting agents, surfactants, adhesives, flavors, sweeteners and preservatives. Abrasive is an important ingredient, generally accounting for about 50% of toothpaste formula. The hardness of the abrasive itself must not exceed the hardness of the tooth enamel. At the same time, the abrasive must have a certain hardness to facilitate the removal of dirt on the surface of the teeth, especially tartar, smoke stains, etc.At present, toothpaste abrasives are roughly calcium carbonate, calcium phosphate, aluminum hydroxide and silica.
Calcium carbonate has strong friction and unstable compatibility with fluoride, which will reduce the foamability of surfactants in hard water; phosphate has good diffusion in the mouth and good adaptability to fluoride, but weak friction; aluminum hydroxide can improve aroma and taste, and has a strong adsorption capacity for toxins, but it is not compatible with fluoride. the specific volume of silica is large, and it is compatible with fluoride and other raw materials in toothpaste, but the cost is higher. Because of its rich micropores, 4A molecular sieves have strong adsorption properties and ion exchange properties. 4A molecular sieves are used as toothpaste abrasives, which are very compatible with fluorine and can preserve effective fluorine ions well. It has attracted people's attention in the daily chemical industry.4A molecular sieve is an aluminosilicate with a porous structure. It has a stable chemical structure and good acid and alkali resistance. It has a strong calcium-magnesium ion exchange capacity, which can effectively reduce the hardness of water and give full play to the role of surfactants. It has a strong adsorption capacity, can directly adsorb a variety of odor gases, high adsorption catalytic activity, and can greatly promote the reaction between fungicides and bacteria.

Storage
Prevent the molecular sieves from exposing directly to the damping environment and any absorption of water or organic substance before it's used, otherwise it must be regenerated.
All Chemequip molecular sieves can be regenerated by temperature or pressure swing.
Delivery
For small quantity order < 100kg, 10 days after purchased contract is efficient.
For big quantity order > 500kg, 15 days after purchased contract is efficient.
